  <pre>Allocates IDs for the given keys, which is useful for referencing an entity before it is inserted.

Args:
  projectId: string, Required. The ID of the project against which to make the request. (required)
  body: object, The request body.
    The object takes the form of:

{ # The request for Datastore.AllocateIds.
  &quot;keys&quot;: [ # Required. A list of keys with incomplete key paths for which to allocate IDs. No key may be reserved/read-only.
    { # A unique identifier for an entity. If a key&#x27;s partition ID or any of its path kinds or names are reserved/read-only, the key is reserved/read-only. A reserved/read-only key is forbidden in certain documented contexts.
      &quot;partitionId&quot;: { # A partition ID identifies a grouping of entities. The grouping is always by project and namespace, however the namespace ID may be empty. A partition ID contains several dimensions: project ID and namespace ID. Partition dimensions: - May be `&quot;&quot;`. - Must be valid UTF-8 bytes. - Must have values that match regex `[A-Za-z\d\.\-_]{1,100}` If the value of any dimension matches regex `__.*__`, the partition is reserved/read-only. A reserved/read-only partition ID is forbidden in certain documented contexts. Foreign partition IDs (in which the project ID does not match the context project ID ) are discouraged. Reads and writes of foreign partition IDs may fail if the project is not in an active state. # Entities are partitioned into subsets, currently identified by a project ID and namespace ID. Queries are scoped to a single partition.
        &quot;namespaceId&quot;: &quot;A String&quot;, # If not empty, the ID of the namespace to which the entities belong.

The entities identified by all prefixes of the path are called the element&#x27;s _ancestors_. An entity path is always fully complete: *all* of the entity&#x27;s ancestors are required to be in the path along with the entity identifier itself. The only exception is that in some documented cases, the identifier in the last path element (for the entity) itself may be omitted. For example, the last path element of the key of `Mutation.insert` may have no identifier. A path can never be empty, and a path can have at most 100 elements.

          &quot;id&quot;: &quot;A String&quot;, # The auto-allocated ID of the entity. Never equal to zero. Values less than zero are discouraged and may not be supported in the future.
